A method of ink-jet printing is carried out by focusing a light beam from a quantum generator onto an expendable liquid printing material in a jet from the direction of the open end of the jet, with an information carrier placed in front of the open end, in order to generate a pressure pulse ensuring the expulsion of a droplet of the liquid onto the carrier. The method is carried out by directing the light beam onto the material in a jet either at an angle to its surface between the jet and the carrier, or through a carrier which is transparent to the wavelength of the beam. An ink-jet printing head has rows of jets, each with one blind end formed in the body of a driving drum. The head is provided with means for feeding the expendable liquid printing material into the jets through their open ends and with means for generating a pressure pulse in the jets, the latter means comprising a quantum generator of a light beam with a device for focusing the beam onto the liquid material from the direction of the jets' open end in front of which the carrier is located, and with a means for deflecting the light beam over the ends.
